Universal scaling of distances in complex networks
Universal scaling of distances between vertices of Erdos-Renyi random graphs, scale-free Barabasi-Albert models, science collaboration networks, biological networks, Internet Autonomous Systems and public transport networks are observed. A mean distance distance between two nodes of …

A new kind of equilibrium in dynamic games with beliefs
We shall introduce a new notion of equilibrium -- belief-distorted Nash equilibrium (BDNE) -- in discrete time dynamic games in which players do not have perfect information about strategies chosen by the other players and …

On the ecological and evolutionary dynamics of prey-predator systems
I will discuss some aspects of the dynamics of interacting populations.In particular, I will talk about oscillatory behaviour and environmentally induced large-scale synchronization (Moran effect) in lattice models of prey-predator systems. More complicated models with …

Introduction to nonequilibrium work relations
Nonequilibrium work relations discovered by Chris Jarzynski are an example of symmetries found recently for several classes of nonequilibrium problems. These symmetries typically connect probability of a given process with that of its "reverse". I …

An attempt of mathematical description of kinematic parameters of hurdles, especially of the hurdle stride
The main objective of this presentation is utilization of mathematical apparatus for description of some kinematic parameters of hurdle race and analysis of position of limbs and of body centre of gravity during hurdle stride. …

Generalization of the Greenspan MCS model to n-dimensional case
In tumour dynamics there is a well known model of spherical growth underthe diffusion of nutrient. The basic concept of multicellular spheroid (MCS) in 3-D was proposed by Greenspan. I'll show the formal generalization of …

Cooperation in Multiperson Prisoner's Dilemma Games - Social Loafing
Social loafing is the tendency for individuals to expend less effort when working collectively compared with when working individually. Such reduction of commonly appearing prosocial behavior was observed in the past by psychologists. Generally, the …

From individual behavior of phytoplankton to evolution equation
Phytoplankton, a mass of small plants (mostly algae) living in the water, comes out to be the main source of nutrient in oceans. That is why understanding of its bahaviour becomes so important and has …

Review on Delay Differential Equations
We introduce the basic notation used in the theory of DDE, formulate the basic theorems and show some examples of the infuence of delays on the dynamics of the system.

Simulation methods for Boltzmann-type equations
We report on the numerical approximation of the solution of a general class of nonlinear Boltzmann like equations. We provide a discretized version of the equations approximating the above class of equations. The numerical implementation …
